Autonomous landing of rotary wing type unmanned aerial vehicles is a challenging problem and key to autonomous aerial fleet operation. We propose a method for localizing the UAV around the helipad, that is to estimate the relative position of the helipad with respect to the UAV. This data is highly desirable to design controllers that have robust and consistent control characteristics and can find applications in search – rescue operations. AI-based neural network is set up for helipad detection, followed by optimization by the localization algorithm. The performance of this approach is compared against fiducial marker approach, demonstrating good consensus between two estimations

Introduction. Fires in high-rise buildings and structures constitute a grave danger both to the people inside, valuables, and the building structure. More often than not, fires develop on the external surface of construction facilities that are in operation or inside those facilities that are under construction, and they give rise to the problem of using standard fire extinguishing solutions and require the employment of mobile machinery by fast response units of the fire-fighting service who apply fire extinguishing agents from the outside of a building. The purpose of this article is to substantiate the in expediency of, or, on the contrary, the need to make the proposed amendments to Federal Law No. 123-FZ of July 22, 2008 “Technical Regulation of Fire Safety Requirements”.The scope of the problem. The analysis of the effectiveness of various methods of application of fire extinguishing agents used to extinguish outdoor fires in high-rise buildings has shown the insufficiently high efficiency of ground-mounted machinery, which preconditions the need to make an enquiry into the possibility of using aircraft to extinguish high-rise buildings and structures. Given the need to ensure effective fire extinguishing, meet safety and economic feasibility requirements, an autonomous unmanned aerial vehicle (AURA) was selected as the delivery vehicle. Systems using various fire extinguishing agents and methods of their application were used for fire extinguishing purposes, including a pulsed water application system, capsules containing the fire extinguishing composition, high-pressure water mist and compressed air foam. Their applicability at the height of 300 meters has determined their choice.Research results. The testing task was to confirm the possibility of application of fire extinguishing agents to the fire seat in the course of the flight of an unmanned aerial vehicle, to identify the effectiveness of fire extinguishing agents and to assess the stability of extinguishing agents applied to the fire seat. To ensure safety, testing was carried out at the height not exceeding 10 m, and the results confirmed the possibility of using the above substances to extinguish fires.Conclusions. The research has confirmed the possibility of using unmanned aerial vehicles and various methods of fire extinguishing by means of the horizontal application of extinguishing agents inside high-rise buildings and structures, if extinguishing agents are applied from outside of a construction facility.

The technology of the fixed wing and the rotary wing unmanned aerial vehicles have been emerging and the applications have been focused widely to numerous regions. This paper focuses on some applications where we have tested our multicopter and in future the further improvement shall incorporate. Our main focus was to build an aerial Covid warrior considering mainly three different and useful applications particularly for remote village areas where many facilities are not always available. First application is the delivery of the medical supplies to the people in need. Second, use of the onboard speaker, which can relay valuable information during emergency or the valuable health related awareness remotely by respective department. And the third application is use of the sanitizer spray arrangement for the larger area disinfection. The prototype has been tested in a typical village area in different conditions and has provided required performance due to optimized design. This paper is to facilitate other users to explore the capabilities of the multicopters for any situations like we suggested with this project considering this pandemic.

Considering that there are promising ways to combat unmanned licensed vehicles for other field warehouses stored in combat situations. The experience of conducting the Joint Forces Operation (ATO) in eastern Ukraine, as well as the negative cases that have recently occurred in the field artillery depots and stationary arsenals (bases) of the Armed Forces of Ukraine, shows that the system of storage of missiles and ammunition in the field artillery depots of The Ukrainian forces are outdated and need major upgrading and modernization. Based on the analysis of the provision of troops with missiles and ammunition, for the period from 2015 to 2016 for the destruction of ammunition storage facilities, both stationary (arsenals, ammunition storage bases of the Armed Forces of Ukraine) and field depots of the units of Incorporated Forces effectively uses unmanned aerial vehicles (UAVs). The most illustrative examples of UAVs are: fire and explosion at the field warehouse of ammunition storage at the combined RAW field warehouses (Svatovo, Lugansk region) on October 29, 2015; attempt to carry out a diversion at the arsenal of storage of missiles and ammunition (Balakley) with the help of UAV December 26, 2015 (dropping packages with incendiary mixture that could not be extinguished by ordinary fire extinguishing means); fire on the territory of the munitions field warehouse on February 18, 2016 of a military unit located near the settlement of Grodivka of Donetsk region (use by a UAV enemy, who in turn dropped the packet with incendiary mixture on the ammunition stack); the fire that occurred on February 17, 2016 as a result of the dropping of incendiary and fragmentation ammunition from the UAV over the rear control post of the military unit (Zaporizhzhia region, Kuibyshevsky district, Vershina village); fire that resulted from dropping explosive devices from UAVs on February 18, 2016 (Cherkasy village, Dnipropetrovsk region). The enemy still uses unmanned aerial vehicles to destroy the ammunition of the Armed Forces of Ukraine. The system of storage of missiles and ammunition in field artillery depots is a set of forces and means, as well as measures of organizational, economic, legal, social and scientific-technical character, aimed at maintaining stable functioning and preventing explosions and fires and losses from them in storage sites and explosives.
